  • Publication number: 20230166105
    Abstract: This specification describes systems, methods, devices, and other techniques for activating muscle groups in a mammal using an implantable epidural electrical stimulation (EES) system, and for using spinal landmarks to determine implant locations for an EES probe. In some aspects, a first set of electrodes of an EES system is provided at a first set of locations on the dura mater of a spine of a mammal, the first set of locations on the dura mater corresponding to a first muscle group of the mammal, a second set of electrodes is provided at a second set of locations on the dura mater of the spine of the mammal, the second set of locations on the dura mater corresponding to a second muscle group of the mammal, and the first and second sets of locations on the dura mater are stimulated by electrically energizing the first and second sets of electrodes.

  • Publication number: 20220241587
    Abstract: Epidural electrical stimulation (EES) systems and techniques for accessing and locating targeted spinal cord segments are disclosed. In some examples, a method includes providing a first set of electrodes of an EES system at a first set of locations on the dura mater of a spine of a mammal, the first set of locations on the dura mater corresponding to a first muscle group of the mammal; providing a second set of electrodes of the epidural electrical stimulation system at a second set of locations on the dura mater of the spine of the mammal, the second set of locations on the dura mater corresponding to a second muscle group of the mammal; and stimulating the first and second sets of locations on the dura mater by electrically energizing the first and second sets of electrodes, respectively, thereby activating the first and second muscle groups in a coordinated manner.
